HEDP Disodium Salt (HEDP.NA2)
HEDP Na2 is an organic phosphonic acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions. HEDP disodium salt can dissolve the oxidized materials, it has good scale and corrosion inhibition effects even under 250°C.
HEDP Na2 is stable under high pH value, not easy to be hydrolyzed. It is also not easy to be decomposed under normal light and thermal condition, its acid or alkaline and chloride oxidation tolerance are better than that of other organic phosphonic acids.
HEDP Na2 has good scale inhibition effects and obvious dissolution threshold effects. At the point when utilized with other water treatment chemicals, the synergistic impacts are better.
Molecular Formula: C2H6O7P2Na2
HEDP Na2 is generally utilized in circulating cool water system, medium and low-pressure boiler, oil field water pipelines as scale and corrosion inhibitor. In different fields such as electric power, chemical industry, metallurgy, fertilizer, etc.
In the woven industry, HEDP Na2 is utilized as a cleaner for metal and nonmetal. In the dyeing industry, HEDP disodium is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP Na2 is used as a chelating agent.
